. l/Vl/E/VTOH 7/21- and 26 serve to operate drums 7-8, while cylinders 23 and 25 operate drums 910.

Engines 24 and :26 are connected to and drive the shaft 91 through its crank wheels 91 and 91 to the crank pins 89 and 89 of which, said engines QG'and 24 are, respectively, connected. Said shaft 91 is provided with a pinion 96, Fig. 2, secured thereto and in mesh with gear 20, secured to shaft 7", on which drum 7 is inovably mounted. Said pinion 96-also drives gear 97, secured to the shaft 8*, on which the drum 8 is movably mounted, as will be clear from Figs. 1 and 2. Engines 25 and 23 drive shaft 92, by reason of their connections, respectively, with the crank pins 90 and 90", on the c 'ank wheels 92 and 92", secured to said shaft 92. Said shaft 92 is provided with two pinions 923 and 9t secured thereto, the pinion 91 meshing with and driving a gear 95, secured to the shaft 10, on which the drum 10 is mo 'ably mounted, while the gear 93, meshes with and drives a gear 22, secured on the shaft 9, on which drum 9 is movably mounted. Said drum 9 has socured thereto, as a part thereof, a gear 21;

. Thus from engines'Qt and Q6, pinion 96,

gear 97, to which drum 8 can be locked at will, gear 20, to which drum 7 can be locked at will, and the pinion 17, loosely mounted on the auxiliary shaft 11, are driven whenever saidengines are operating. From engines and 23. through shaft 92, pinion 91, gear 95, to which drum 10 can be locked at will, pinion 93, gear 92. to which-drum 9 can be locked at will, and pinion 19, secured to the auxiliary shaft 11, and said auxiliary shaft 11, are all driven whenever said engines 25 and are operating. Drum 9 is capable of being operated at two different speeds, that is, when friction clutch :29 is operated, the gear 18, loosely mounted on shaft 11, is locked to the friction clutch 28, secured to said shaftv 11. and as said gear 18 is in mesh with the. gear21,fornied as a part of drum 9, said drum 9 will be driven at high speed. \Vhen friction clutch 9 is operated, said drum 9 is locked to the gear 22, and is driven from the pinion 93, on the crank shaft 92, at low speed. To drive drum 8 from engines 2-iand 26, it is only necessary to operate its friction clutch 8 which puts it. in driving connection with the gear 97, driven from the pinion 96, see Fig. 2. if it is desired to add to this drum 8, the power of engines and 23. then it is only necessary to close friction clutch 30, thus connecting engines and 23, through their crank shaft 92, pinion 93. gear 22, pinion 19, shaft. 11, pinion 17. which is locked to shaft 11 by said clutch 3t), and gear 20. If itis desired to drive drum 7 from engines 24- and 26. it is only necessary to close friction clutch 7, which locks said drum 7, to its gear 20, which is being driven from the pinion 96,

on the crank shaft 91. If it should be desired to add to this drmn the power of engines 25 and '23. it is only necessary to close friction clutch 3 as before described, the drive from engines 25 and 23 to and through the shaft 11 being the same, pinion 17 being locked to the shaft 11 by said clutch 30. To drive drum 10 from engines 25 and 23, close friction clutch 10. If it is desired to add to this the power of engines 2t and 26, close the steam friction clutch 3t), whereupon the drive from crank shaft 91, of said engines 2% and 2G, is transmitted through the pinion 9G, gear '20. pinion 17, now locked to the shaft 11 by steam friction clutch 30, pinion 19, gear 2;, pinion 93, shaft 92, pinion 91: and gear 95. to which said drum 10 is locked. Drum 9 can be driven from engines 25 and by operating the steam friction clutch 9", which locks it to gear 2'2, driven fromthe pinion 93, thus driving it at low speed. If it is desired to drive drum 9 at high speed, steam friction clutch 99 is operated, which locks gear 18. to the shaft 11, said gear 18 driving said drum through its gear 21. The power of engines 2t and 26 can be added to said drum 9 by the closing of the steam friction clutch 23th as before. \l'hen engines 25 and '33 are operated, the shaft 11 is always driven by reason of the connection of its pinion 19 with the gear 2; which meshes with the pinion 93 on the crank shaft of the engine. When engines l t and 26 are ope 'ated, the shaft 11 is not driven from these engines unless the steam friction clutch 30 is operated so as to lock pinion 17 to said shaft 11.

Thus by means of the train of gears from each of the engines to the auxiliary shaft 11. all of the powerof all of the engines may be connected up to any one. drum, when required by an unusual load thereon.

The means of piping the steam-frictions and engines from the boiler are old in the art and need not here be described in detail, particularly as they form no part of the present invention. The mode of operating said engines andsteam-frictions is also ld, and therefore will only be referred to casually. hereinafter.

'In Fig. 12 is shown a form of rigging used in connection with the above described arrangements of engines and drums, known in loggers parlanc as a yarding system, while Fig. 13 illustrates a form of rigging known in the art as a sky-line, or an aerial svstem. 'lhese systems in connection with the. novel structure of the anx iliary shaft and parts. attached thereto, form the subject matter of the broad claims of this invention.

2mm 0f the steam brakes and the valves that operate same. The following brief description will suflice to explain the same Main steam-pipe 75 is attached to any suitable place on the boiler, from whence it passes downwardly to manifold 76, while pipe 77 passes from-said manifold to brakecylinder 78; pipe 79 passes to brake-cylim der 80; pipe 81 to brakecylinder 82 and pipe 83 connects with brake-cylinder 84. The steam is allowed to pass into these brake-cylinders through the medium of valves 858687 and 88 respectively.

The means of connecting engines 89 with crank-pins 8989 and engines 90 with crank-pins 00 -90 are not shown, but are well known in the art and form no part of the invention. hen said connections are made, crank-pins S9 89 drive crank-shaft 91 through the medium of cranks 9191 ,while cranlcpins 90-00 drive crank-shaft 92 through the medium of cranks 9292 Mounted on said crank-shaft 92 are pinions 93-94, which inter-mesh with gears 22 and 95, while a single pinion 96, is attached to crank-shaft 91; said pinion intermeshing with gear 97.

Passing transversely of base-plate 2 are brake-shafts 9899 (Fig. 1); the brakelcvers 100-101 being attached to brakesha ft 98 for the purpose of operating brakeband 102 of drum 10, (Figs. 1 and 5), and brake-band 103 (Fig. of drum'S, while bralrcdevers 104105 connect .0 brake-shaft 99; the brake-lever 10+ o 'ierating brakeband 109 of drum 7, and brake-lever 105 operating brake band 108'of drum 9 (big. 4).

By the use of the brake-cylinders and other operating mechanisms above described, one man can operate the engines, while another man in the woods gives tluproper sig nals to said operator.
